Specification of Letters Patent.

Patented Apr. 9, 1912.

Application led March 13, 1911. YSerial No. 614,227.

To all 'whom t may concern: f f

Be it known that I, CARL J. WALLEN, a citizen of the United States,'residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Window Construction, of which the following is a specication.

This invention relates to improvements in window construction, and is especially an closed; to provide means forv locking the said sashes in closed position; to provide means for adjusting the sashes vertically or to raise or lower same; and to allow the sashes to vbe swung inwardly when desired for convenience in cleaning same.

The invention is embodied essentially in a window casing having the upper sash vertih cally movable therein by means of projections sliding in a vertical slot at each side of the casing and a lower sash slidable similarly in a parallel slot at eachside of the casing. Means are provided for shifting the lower sash below the upper one when lowered, and a locking-strip is adapted to swing against the said sashes when arranged one beneath the other to securely lock same in such position. Means are also provided for allowing the said sashes to be swung inwardly when desired.

This invention comprises a novel arrangement and construction of parts as herein* after described, and as shown in the accompanying drawings, in which similar refers ence characters indicate similar parts, and in which- 1 Figure 1 is a perspective of a window casing embodying my improvements. Fig. 2 is a vertical 'section of the casing, showing in dotted lines the lower sash partly swung inwardly. Fig. 3 is a section on line 3-3 of Fig. 2. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5 is a section on the line 5-5 of Fig. 2. y

Referring specifically to the drawings, the window casing is indicated at 25, the upper sash at 6 and the lower sash at 7. To the sides of the casing are secured flat strips 15 which have two verticaland parallel slots or grooves 10 and 14 therein.. The upper sash has upper projections 8 to which are attached at each side the sash-cord 11, and lower projections 9. These projections 8 and 9 are slidable in the slots 10 and therefore allow for the raising and lowering of the said sash. Both sides of the window are similar in construction and for this reason only one side was shown in the drawings.

The lower sash has the upper projections 8 Y and the lower projections 9, the sash cords 11 being secured to the upper projections. The sash cord 11 runs in the slot 10 and the sash cord 11 runs in the slot 14. The proe jections 8 and 9 are slidable in the slots 14 and allow for the raising and lowering of the lower sash. The sash-cords each run over the upper pulley 13 and'have a weight 12 attached to the free end as is common in window construction. Various other balancing means for the'sashes can be provided.

A locking-strip 16 is hinged to each strip 15 on its inner edge at 13 18 and is adapted to swing to and from the sashes. The transverse slot 23 of each strip 16 which eX- tends from the slot 10 to the inner edge thereof and which intersects the slot 14 is arranged to come in alinement with the slot 23 of the locking-strip 16 when the same is swung outwardly to lie tlush with the strip 15, thus forming a slot 23 from the slot 10 to the inner side of t-he casing. The lower end of each of the slots 14 on the respective sides of the casing extends or passes beneath the ends of the slots 10, to bring the lower end of the sash 7 below the upper sash 6 when lowered to the bottom and to overlap the sill board 24. The upper end of the sash 7 can then be swung in under the sash 6, the projections 8 passing along the slots 23 to the slots 10. When in this position the lock= ing-strip 16 canibe swung against the said sashes to securely hold same in that position and to make it impossible to open the window from the outside. Fig. 4 shows the lockingstrip as swung against the sashes and Fig. 5 shows the same as swungagainst the side of the casing or flush'with the strip 15. A packing strip 17 on the free edge of the locking-strip 16 assists in making a tight joint between the sashes and said lockingf strip 16. A Hap on each of the strips 16 makes it convenient to swing `the said strips 16 out of their locked position.

A plate 20 pivoted in each side of the casing at 21 adjacent to each of the slots 23 is arranged to be swung out by means of the tension of spring 22 to close the opening formed by the slots 23 and 23 lVhen the locking-strip is swung against the side of the casing the said plate is forced back against the side of the easing, as shown in Fig. 5.

It will be seen that`- the respective sashes can be slid up and down in the grooves or guide-slots l() and 14 when the lockinU-strip is opened or swung out of locked position, and that they are brought one beneath the other when closed to allow same to be locked by the strips 16. It is also possible to swing the upper end of the lower sash 7 inwardly`r as shown by the dotted lines in Fig. 2, the projections passing out groovesv 23, to allow the outside of the window to be cleaned from the inside. The upper sash can also be lowered and swung inwardly in a similar manner over the lower sash.

Various accessories can be used with this form of window, which are not shown. It will also be seen that when in locked position, the sashes are brought tightly against the lock-beads 26 to make the window air tight and non-rattling. Various alterations can be made to this device within the scope of the appended claim.

Having described my invention, what I claim as new isi A window construction comprising in combination, a casing having' pairs of vertical slots at the sides thereof and a slot intercepting each pair, and one slot of each pair formed with a lower portion extending under its adjacent slot, an upper sash having projecting pins engaging a slot, and a lower sash having a pin in one slot and a lower pin in the extended portion of the other slot, a hinged locking strip to engage said sashes when arranged one above another, and formed with a slot in line with the intercepting slot whereby the lower sash may be swung inwardly on its lower pin as a pivot and its upper pin traveling in the slotted strip.

In testimony whereof I do affix my signature in presence of two witnesses.

CARL J. VALLEN.
